Grain Mill Drill Question

I have a Milwaukee 12 Li ion cordless, keyless chuck. The battery is small, but I’ve done up to 36 pounds through the mill, double crush (one at 0.060”, one at 0.025”) without running the second battery out. As mentioned above, I run it in low gear.

 

Beefy Makita 1/2" corded drill on my MM2. Haven't taken it off the drive shaft in 2 years. It's a beast.

 

I use a corded Bosch, full speed, locked into drill position. I want to take my extra rock tumbler and hook it up on a stand tho.

 

Full speed huh? Any particular reason you don't want a slower mill?

 

18V Craftsman cordless here... just remember to keep the battery charged! Crushing by hand isn't really that hard but it adds some time to the brew day.

 

My 12V Bosch has done a fine job with my Monster Mill over the years. It took two of the original NiCd batteries, fully charged, to mill 20# of grain. I bought a 3Ah NiMH battery a couple years ago and can now do it with one. 18V would probably be better, but this gets the job done, so there's no rush for an upgrade.

It was out on loan one brew weekend a couple years ago, so I picked up a $20 corded drill at Harbor Freight on my way home from work. It smoked and barely budged. I haven't touched it since. I ended up using the hand crank, which wasn't nearly as much of a chore as I expected.
